Question #75656
Assessing the Speciation of Bromomethane and Atrazine in Quartz Sand
Consider a confined volume of pure quartz sand exposed to air (RH = 45%), with a porosity = 0.5 (see Box 5.4) a density of 2.65 g cm-3 and a surface area A = 1 m2 g-1. What fraction fia of (a) the fumigant bromomethane and (b) the herbicide atrazine will be present in the pore air at 15 ˚C and at 35 ˚C assuming a linear adsorption isotherm?
Hint: Consult Box 11.1 Use Eq. 11.4 for estimation of the adsorption enthalpy of the two compounds.
